DEVICE FOR OPERATING OIL GAUGES.

Application filed January 19, 1924. Serial No. 687,379.

To all whom it may concern:

Be it known that I, Jon W. BLACK, a citizen of the United States,residing at Chicago, in the county of Cook and State of 6 Illinois, haveinvented a new and useful Improvement in Devices for Operating OilGauges, of which the following is a specification.

This invention relates to devices for operating oil gauges and the likeand is particularly adapted to be used on Ford cars where the two oillevel gauges are very inaccessible.

The primary object of the invention is to provide a device which willmake it easy to open and close these oil gauges, which is positive inits action, and which at the same time while being substantial andsatisfactory in its operation, is relatively inexpensive to manufactureand install.

These and other objects as will appear from the following descriptionare fully described in the following specification and shown in theacompanying drawings in which:

Figure 1 is a partial transverse vertical section through an automobilechassis showing my device applied thereto;

Fig. 2 is an enlarged side elevation of the U-shaped operating member;and

Fig. 3 is a top plan view of the same.

This is an improvement on the construction shown and described in mypending application Serial No. 633,214., filed April 19, 1923.

The Ollll'lOdllllGIlt illustrated comprises a Ushaped sheet metaloperating member 10 having openings 11 in its ends, these openings beingadapted to be placed over the flattened ends 12 of the tapered plugs ofthe petcocks 13 which are commonly placed in thecrank case 14.- of aFord substantially as shown in Fig. 1.

The petcocks 13 are turned so that the plugs 12 are in alignment andface in the same direction, the flattened ends of the plugs 12 beinguppermost. The openings 11 of the U-shaped member 10 are adapted to beplaced over these flattened ends and may then be securely fastenedthereon by being squeezed together at 15 as by means of pliers.

A rod 16 has one end bent at 17 and adapted to pass through a hole 18 inthe member 10. A cotter pin 19 passes through the end of this rod andretains it in the hole 18. The opposite end of the rod 16 passes throughan opening in the running board shield 20 and has a knob 21 secured onthe outer end as by means of a cotter pin 22.

A spring 23 passes over the rod 16, one end of the spring bearingagainst the inner side of the shield 20 while the opposite end bearsagainst a washer 2 1 which is secured on the rod 16 by means of a pin25. This spring is under compression at all times so that the U-shapedmember 10 is normally held in the closed position shown.

When it is desired to test the level of the oil in the crank case 14,the operator takes hold of the knob 21 and drawing it outwardlycompressing the spring 23 and causes the U-shaped member 10 to turn theplugs 12 thereby opening the petcocks 18. The observer then looks underthe running board 26 to see what oil is running from both petcocks 13.From the observed flow he is able to judge of the level of oil in thecrank case. Oil will flow as long as the knob 21 is held out, therebymaintaining the petcocks open. As soon however as he releases the knob21 the spring 23 forces the rod 16 and the U-shaped member 10 back tothe position wherein the petcocks are closed.

Because of the inclined positions of the petcocks an outward pull of therod 16 in addition to turning the plugs 12 also has a tendency to pullthem outwardly against the action of their springs 27. As the plugs 12are tapered, the larger end being upward toward the flattened ends 12,this has a tendency to loosen the plugs and prevent their stickingduring the operation of opening them. During the reverse operation ofclosing the pressure of the rod 16 tends to force these tapered plugstoward their seats, thereby insuring that they are properly closed.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changestherefore in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as possible in view of the priorart.

I claim: tion, the plugs being inclined toward the A device foroperating two crank-case operating means, so that said operating 10peteocks having aligned plugs pointing in means tend to Withdraw thetapered plugs the same direction, said device comprising a as they areturned toward open position and 5 member adapted to engage said plugs,means to force said plugs into the peteoeks as they extending to anaccessible point for operare turned toward closed position. ating saidmember, and a spring for retnrning said member to a normally closedposi- I JOE W.
